These are some of the more common questions that we receive regarding Garwood Water Service and its operation. If you don't see an answer to your question please drop us a note.

  • Why does this have to be done annually?
    This has to be done annually because backflow devices just like everything else do fail. The state requires that they be tested annually.
  • ​What if I don't have a sprinkler system?
    For the residences and homeowners in our system, the main compliance will be anti-siphon hose bibs and sprinkler systems. If your house is less than ten years old, chances are you already have anti-siphon hose bibs. If you don't have a sprinkler system, than your next concern will be the hose bibs on your house. If your hose bibs are not anti-siphon, an adapter can be purchased to screw on the end.
  • Who controls the costs involved in having our backflow devices tested?
    Unfortunately, the costs involved in having backflow devices tested rests solely on the shoulders of the testers doing it. Hopefully, with all community water systems completing backflow testing, the prices will stay competitive.
  • What if I refuse to comply?
    The State Administrative Code says this: Discontinuance of water service to any facility where suitable backflow protection has not been provided for a cross connection. Everyone that refuses to comply is only endangering themselves as well as the other patrons of the district.
  • How much does it cost to have backflow devices tested?
    The typical range of cost for having your backflow device tested ranges from $25.00 to $70.00. If your backflow device is need of repair, then you can expect to pay additional costs which will be different for each individual device. All of this will be determined of course by the certified tester that you contact.
  • How do I know if my property complies?
    If you are unsure of whether or not your property complies, you can contact a licensed tester and get a property evaluation, or you can call us and have us evaluate your property. If your property already complies, and you have no testable backflow devices that are needed, then you are basically done with the program until you decide to add something that needs a backflow device such as a sprinkler system.
  • ​For those who already have backflow devices, will we just simply be required to have them tested?"
    Yes. If you already have the proper backflow devices you will just need to have them tested annually by a licensed tester.
